Abstract
Abstract A six-wheel armored vehicle has each wheel driven by an engine mounted between the front wheels and to the side of a driver's station disposed in the beveled shaped nose of the vehicle. Terrain in front and to the sides of the vehicle may be viewed by a driver from within the vehicle by a plurality of periscopes. Alternatively, a hatch opening in a forward sloping surface of the nose immediately behind the periscopes permits the driver to raise his head out of the vehicle in order to view the terrain. A fuel storage tank is formed integral with rear portions of the vehicle's hull and comprises a plurality of interconnected fuel cells defined by double wall construction of the hull body. A fresh air inlet and deflector arrangement in the upper horizontal surface of the hull delivers fresh air forwardly to an engine compartment for cooling the engine, and warm air generated by the engine is reversed in flow direction and exhausted via a conduit through an outlet opening immediately adjacent the fresh air inlet.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
249 words
An armored vehicle comprising: A. A hull having a front end, a rear end, lateral side walls, and a top wall defining an enclosed interior space including an engine compartment defined in the front end of said vehicle at one side of the hull and a driver's compartment defined in the front end of said vehicle at the other side of the hull along-side said engine compartment, said front end of said hull including an upper sloping wall blending at its upper rearward edge with the forward edge of said top wall, said engine compartment extending into said front end of said vehicle beneath said upper sloping wall; B. Wheel means supporting said hull; C. An engine mounted in said engine compartment and drivingly connected to said wheel means when normally propelling said vehicle for travel in a forward direction; D. An air inlet opening in said top wall rearwardly of the blend joint between said upper sloping wall and said top wall; E. An air exhaust opening in said top wall rearwardly of the blend joint between said upper sloping wall and said top wall and along side said inlet opening; F. An engine cooling system including air circulation means operative to draw air in through said inlet opening, move it forwardly in said engine compartment over said engine, reverse the air flow direction, and move the air rearwardly for exit through said exhaust opening; and G. A hatch in said upper sloping wall overlying said driver's compartment.
Claim 2
Dependent Claim
249 words
An armored vehicle comprising: A. A hull having a front end, a rear end, lateral side walls, and a top wall defining an enclosed interior space including an engine compartment defined in the front end of said vehicle at one side of the hull and a driver's compartment defined in the front end of said vehicle at the other side of the hull along-side said engine compartment, said front end of said hull including an upper sloping wall blending at its upper rearward edge with the forward edge of said top wall, said engine compartment extending into said front end of said vehicle beneath said upper sloping wall; B. Wheel means supporting said hull; C. An engine mounted in said engine compartment and drivingly connected to said wheel means when normally propelling said vehicle for travel in a forward direction; D. An air inlet opening in said top wall rearwardly of the blend joint between said upper sloping wall and said top wall; E. An air exhaust opening in said top wall rearwardly of the blend joint between said upper sloping wall and said top wall and along side said inlet opening; F. An engine cooling system including air circulation means operative to draw air in through said inlet opening, move it forwardly in said engine compartment over said engine, reverse the air flow direction, and move the air rearwardly for exit through said exhaust opening; and G. A hatch in said upper sloping wall overlying said driver's compartment.
Claim 3
Dependent Claim
80 words
An armored vehicle according to claim 1 wherein said air circulation means includes: H. A cooling fan positioned at the front of said engine and arranged to pull air through said inlet opening and forwardly over said engine; I. An air reversing chamber defined within said hull forwardly of said fan; and J. An air conduit communicating at its forward end with said air reversing chamber and extending rearwardly therefrom for communication at its rearward end with said exhaust opening.
Claim 4
Dependent Claim
25 words
An armored vehicle according to claim 2 wherein said air conduit is defined in part by one of said lateral side walls of said hull.
Claim 5
Dependent Claim
37 words
An armored vehicle according to claim 2 wherein said air cooling system includes a radiator positioned beneath said inlet opening in the path of cooling air flowing through said inlet opening for rearward passage over said engine.
Claim 6
Dependent Claim
55 words
An armored vehicle according to claim 1 wherein said air circulation means includes: H. Inlet deflector means positioned in said inlet opening and operative to direct air downwardly and forwardly into said engine compartment; and I. Exhaust deflector means positioned in said exhaust opening and operative to deflect air laterally away from said inlet opening.
Claim 7
Dependent Claim
300 words
An armoured vehicle comprising: A. A hollow hull including lateral side walls, a generally horizontal top wall and a beveled front end defined in part by an upper sloping wall blending at its upper rearward edge with the forward edge of said top wall; B. A water-cooled engine positioned in and at one side of said hull with its forward end projecting into said front end of said hull beneath said upper sloping wall; C. A driver's compartment defined in said hull along-side said engine; D. Air inlet and air exhaust openings defined side by side in said horizontal top wall rearwardly of the blend joint between said upper sloping wall and said top wall and rearwardly of said engine, said exhaust opening being positioned adjacent said one side of said hull and outboard of said inlet opening; E. A radiator positioned in said hull beneath said inlet opening; F. A reversing chamber defined in said front end of said hull forwardly of said engine and beneath said upper sloping wall; G. A longitudinally extending conduit formed in part by the lateral side wall forming said one side of said hull and communicating at its forward end with said air reversing chamber and extending rearwardly therefrom for communication at its rearward end with said exhaust opening; H. A fan positioned at the forward end of said engine and arranged to draw air through said inlet opening and pull it downwardly through said radiator and then forwardly over said engine for passage into said reversing chamber and subsequent rearward passage through said air conduit for ultimate discharge through said exhaust opening; and I. Exhaust deflector means positioned in said exhaust opening and operative to deflect exhaust air to said one side of said hull and thereby away from said inlet opening.
